Spread spectrum communication is a kind of technology,extending many times the bandwidth of information to communicate.And it has strong anti-interference,is good for hiding,has anti-fading and multi-path fading,is easy to implement code division multiple%扩频通信是一种将信息的带宽扩展很多倍进行通信的技术,它具有较强的抗干扰、低截获性、抗衰落和抗多径性能,易于实现码分多址的特点。着重叙述了扩频通信的理论基础、分类、特点。介绍了m序列的本原多项式和它的产生方法,同时应用Simulink建立了常用扩频码序列m序列的仿真模型。
